Mopeds at dawn pumpkin!

Nothing spookyer than a moped in the moonlight!

Second hand 103 parts

Got hold of an old 103 motor with carb and exhaust. Also a thicker 103 rear mudguard. Will use the engine for spares and fit the mudguard to replace the skinny bent vogue one. I think I'll paint it black.

Tomos A3 engine swap (part 2)

After borrowing Sinclairios Deep well socket I removed the cylinder and piston from the A3 motor.
























Then I offered up the Airsal gasket to the A35 cases and marked the amount to be removed from the cases with a permanent marker. I was a bit worried how close the marker came to the edge around the top so I decided I would remove all of that.
























Next I attacked it with the dremel here's a shot from half way through.
























And here it its is all done!!

 

  

Gurtner idle fix!

After coming across this web site:

http://www.myronsmopeds.com/category/service/carburetor-service/



















I read that the idle pathway needed to be drilled out with a #71 jewellers drill bit. So I ordered a couple.
















When the drill bits arrived they fitted in my small rotary tool. So I used the bit to drill down through the air bleed hole and through the brass fitting and out the other side creating a new idle pathway.
















I tested the new idle pathway with carb cleaner and saw it spray out in the correct place so I reassembled the carb and fitted it back on the vogue.

 

And it works!!!

Tomos A3 engine swap (Part 1)

Today I made a start on the first leg of swapping my old A3 engine for a rebuilt A35. So first off I removed the foot pegs and the chain. I think I may buy a new chain as mine is unusually oily. Next I removed the new Homoet pipe and noted the scratches and dents in the underside from wheeling it up and down the steps to my shed. I removed the carb and tied it up in a plastic back to keep it from getting dirty. I drained the oil and then decided it was time to remove the engine so I disconnected the electrics and undid the three bolts holding the motor on.



















The only problem was that the petcock was preventing the motor from swing down and off the bike. So I had to drain a full tank off fuel before removing the petcock so I could get the engine off.

So next I moved the motor over to the work bench next to the A35 cases.



















I need to transfer the 70cc Airsal kit off the A3 and onto the A35 but before I do that I want to case match the A35 to the Airsal kit as I didn't do this when I fitted the kit to the A3 and it should make the A35run a bit better.



















Before I did this I just thought I would check the condition of the reed in my Malossi four petal reed block. It turns out that one petal was ever so slightly open so i will need to order a new reed.

I then realised I didn't have a 10mm deep well socket to remove the cylinder nuts so I will have to pick one up tomorrow.

New dremel tips!

Sinclairio noticed these is our local lidl for only £5 so of course i had to get a set.

Ball joint separator!

Picked this up this morning as i think it will be useful for separating the bearings from the crankshaft.

Gurtner idle problems

So i did a bit of research and came across this page that has an explanation as to why the Carb won't idle. Its all do with the idle pathway being tiny and getting blocked. It needs to be drilled out with a jewellers drill. So will see if this solves the problem.

Cleaning Gurtner Carb

Im still struggling to get the Peugeot to idle. So i thought i would take the Carb off and give it a clean.

Almost ready to case match!

So I've removed the bearings and seals from the two A35 crank case halves and bolted them back together in preparation to to case match them to my Airsal 70cc cylinder. Just need to removed the cylinder carefully from the A3 motor and borrow Sinclairio's dremel.

Motor stand

So with winter fast approaching my attentions have yet again fallen to the E50, my bug bear, I've spent a fortune in it, hours changing bits and still no joy! So I've invested in a stand so I (cookson) can work in the bench and be able to access all angles properly with out damaging it. I'm going to buy all new gaskets, crank seals again, sparky, etc... At the moment It lies idle in a bucket polished & case matched with a brand new racing crank 70cc head on! Just doesn't work!

A35 tuning parts from YPVS!!

Whoop whoop new parts for my A35 build have arrived thanks to Martin from YPVSpares.com

103 idles

So I figured out that its definitely the mixture is off because of the lack of the air filter. If i put my finger over half the carb to restrict the airflow it idles lovely. The choke is controlled off the handlebars so with my thumb on the choke it idles. Rode it up and down the road and its an animal not sure how fast as no speedo.

103 up and running

I had a bit of time this morning so thought i'd see if i could get the peugeot up and running. First i removed all the plastic engine covers (see photo) then i mixed up some two stroke and put a bit in the tank. When i turned the petcock the fuel flowed into the carb. So i put the bike on its centre stand and peddled like mad and it fired up. It doesn't seem to want to idle and dies unless i rev it but i expect it because the airfilter is missing or the carb just needs adjusting.
Once i have it idling i will post a video.

103 build at warp eight!

My Peugeot 103 Vogue

Finally made it back to see my folks and got my hands on the 103. Looks to be in great condition. Needs a new rear brake cable. I will try and rustle up some 2stroke over the weekend and get it running.
